He didn't say there was a shortage, he said we have used up all the easily accessible resources. The resources left need a lot of technological advancement to get at, which we won't have if we *need* to ignite a second industrial revolution.

Yeah, and all the user has to do is place in *a single non-english phrase* from their favourite fantasy book/dream destination/scifi series/song and they've suddenly broken the attackers ability *as well as* possessing a password that they can easily remember. "correct horse? je t@ime staple" is almost never going to be broken. Nor is "correct horse? luke's lightsabr3 staple", nor "correct horse? fr0do of the shire staple", etc...

All of those are easy to remember, easy to type in but still orders of magnitude harder to break than "8 printable chars " or whatever nonsense the IT department came up with last week. Go ahead - try your rainbow table dictionary attack against "correct horse? samuel vimes 0f ankh-morpork staple" and let us know how it goes. We'll wait.

I note that you aren't addressing the fact that Ms Wu herself has no record of filing a case. You can claim police incompetent all you want, but you have no actual fact to back up the claim of police incompetence. Rather than claim a grand conspiracy, I'd prefer to stick with the known facts instead of who claims what. The only fact that remains is that Ms Wu has no record associated with filing a case.

FWIW, now that the case presumably *is* filed, there is apparently not enough credibility in her claims to pursue, which makes you whole argument about whether she is lying moot.

Nope, I pointed out (politely, mind) that he found *some* way to work his personal belief system into the conversation. Proselytizing is almost never welcome.

Hmm... He said...

Because... that's the correct way to respond to someone being dismissive? I can see why CS is an attractive and desirable place for females...

BTW, this thread is an excellent example of why females aren't happy in the CS environment. I plan to link to it the next time some forward thinking intellectual goes on about CS being female-hostile. It's just plain hostile to everyone. If women can't handle being called knob-ends then they don't belong, right?

Insults, derision, micro-aggression - yup! We don't have a clue why there aren't more females in CS.

Well, that just it, isn't it? Absence of an ideology is the same as absence of a religion - just because I contradict your ideologically-driven claims doesn't mean that I have an ideology of my own, in much the same way that just because I contradict claims of a god doesn't mean I have a god-based claim of my own - "baldness is not a hair colour".

Nope. You send your little insults my way and, like the way I deal with all theists, I stick to what facts are known.

Doesn't sound like that at all - there is no ambiguity from LEO's statement - no report was filed. They did not say a report was *lost*, or *miscommunicated*, or anything. Not only did they say that no report was filed, they go further and say that there was no contact from Ms Wu either. She neither contacted them nor filed a report. By her own accounts, she never had a case number either (meaning, it was never filed with the police).

That's a god-of-the-gaps argument if I ever saw one - "If there is no evidence connecting $X and $Z, then it *MUST* be this thing-that-can't-be-proven $Y. Our evidence exists in the gaps between the steps." Face it - if she at least had a case number, or the name of the officer who took down the report, hell... even the *date* she claims she made the report she might be believable. She has no record of ever approaching the police, no case number nor a name or description of the officer who helped her. The LEO's are standing firm on this as well - they have no record.

Where did we claim that? I personally claimed that, according to all the evidence that we have, there is no record of her approaching the police - none that she can provide and certainly none that the police can provide. If she wanted her claim to be taken seriously she should have at least kept the case number you get for filing an incident with the cops.

In this case at least, there is little doubt that she lied.

I honestly thought that was the difficult part; it's halting-problem hard, if I understand correctly. If you cannot predict whether a program will ever reach the end-state, then you cannot predict if it will ever reach *any* particular state. To know whether to prefetch something requires you to have knowledge about the program's future state.

To my knowledge prediction of program state only works if your predicting a *very* short time in the future (say, no more than a hundred instructions). If you're limited to that then the best you can do is branch prediction or similar (only a few hundred instructions?). This is why the cache helps - if you use something then the probability is high you will use it again soon. Compilers can then take limited advantage of this by locality of variables/instructions.

It's the negation of the problem of deciding what *will* be needed in some future state. This makes it equally hard (halting-problem hard) to deciding what to prefetch. For both problems it appears to me that computer science has already settled on "no solution" as the answer to the question "can we predict the programs future state?". NP-hard is NP-hard, no matter how much engineering talent is thrown at it; it remains mathematically impossible. Hence, I figure that what this kid has got is some great new mitigation scheme for program state prediction. That, or maybe he skipped the automata theory classes (I see that a lot with engineers-turned-programmers).

(I think - feel free to correct my understanding).

Yes. She is *literally* lying now, like she *literally* *lied* all those other times. This is the official response from law enforcement

... from the same link ...

... and yet, it seems the only credible danger was *to* GG *from* anti-GG ...

Be plain. Vague insinuations are a scoundrel's game.

Plainly? The only credible aggression is from the ideological crusade side. Hell, even on /. the only non-AC aggression is from SJW who are the first to post aggressive, name-calling, verbal abuse and (in cases involving poperatso) actual threats. Not that I find the threats credible, but that's *your* side that needs to learn how to communicate like adults. Maybe you should deal with the aggression coming from your ideological partners before asking the rest of the world to do so first.

I'm in agreement - experience counts for a lot when doing something new.

I'm in agreement with this as well.

It is highly unlikely that this will go anywhere (so, yeah - agreement again)... BUT... he is displaying a great deal of talent for his age. The lessons he learns from this failure[1] will be more valuable than the lessons learned in succeeding at a less difficult task.

As I understand it, he proposes removing the hardware cache and instead using the compiler to prefetch values from memory. He says the hardware cache logic gates add 40% overhead to every memory fetch. Whether he can actually produce a compiler than will insert the necessary memory fetch instructions at compile time in an efficient manner remains to be seen, but it is still a worthwhile endeavour for a 19 year old.

[1] Worst case scenario. He might succeed after all.

Or perhaps she's claiming that the threats were so non-credible that no cause for investigation could be found. Cops *wanted* to investigate but apparently there wasn't anything of substance *to* investigate. It's easier to investigate when there is, you know, actual evidence of a credible threat.

You might have answered this already but I'm not very good at reading walls-o-text, so apologies if this is a repeat: The hardware managed cache design for chips is popular for a reason - it provides a speed boost. If you remove this what kind of process do you propose to replace it with? (Unless you have a design that makes a hardware managed cache redundant. What do you do then? Have software manage the cache?)

He's young, and he displays much more talent than people twice his age. What's your problem anyway?

I'd imagine that a 19 year old as impressive as he is pretty much has the sexual choice of anyone (male or female) that he wants.
